IMPROVEMENT IN SPF-.RING BED-BOTTOMS.

Specification forming part of Letters Patent No. 149,149, dated March 31, 1874; application filed July 30, 1873.

To all whom it may concern:

Be it known that I, BENJAMIN H. OTIs, of Havana, in the county of Mason, and in .the State of Illinois, have invented an Improvement in Spring Bed-Bottoms granted to Ine by Letters Patent of the United States, J anuary 9,1872, No. 122,645; and do hereby declare that the following` is a full, clear, and exact description thereof, reference being had to the annexed drawings making a part of this specification, in which like letters of refeTence refer to like parts, and in which- Figure l represents an end elevation; Fig. 2, a longitudinal elevation along dotted line a. a', Fig. l, Fig. 3, a perspective view of one ot the sla-ts E E, &c. 5 Fig. 4, perspective view of 011e of the inclined springs B B; Fig. 5, perspective view of 011e of the fulcrum-blocks c c.

This invention relates to a peculiar construction and combination of devices, as will be hereinaftermore fully explained, and pointed out in the claim.

In the drawings, A A represent two movable cross-bars, (movable within the bedstead sides,) and having at each end a block, b, surmounted by a short pin, yi, to receive the slot in one of the inclined springs B B. These latter are placed in pairs at either end of the bed-bottoni, their upper ends having each a recess cut in the under surface to rest upon a horizontal pin engaged in the retaining loop or clip d. (I also use a single clip instead ot' two, to inclose the united heads of these springs B B, to connect them with the straight spring C.) Through the upper part of the loops d d l d, at each end ot' the bed-bottom, passes a straight spring, C O, the ends of which are secured in a recess in either of the blocks c e, between the bar D and spring B, or be secured by a pin and slot, bolt, or equivalent fastening. i These springs C C may be placed with equal advantage within the clips d d and be low the levers B B. The bars D D each rest upon the fulcrum-bloeks c e below them, and to which they are fastened; said blocks have also a short pin or nipple, 7c lo, on their under surface to enter a hole in the respective springs B B B B. 'Ihe bars D D, further, are provided with a row ot' vertical pins, n, on their upper surfaces, to hold the bed-slats. The lat- Yter, E E, 85e., have corresponding holes S at one end, and slots z at the other to adapt them to the length of the bed-bottom or distance between the bars D D. The outer bedslats E E', one at 'each side, have no slots, but have a row ot' holes at both ends in order to tie the bars D D and prevent the bed-bottom from spreading These slats are all kept down by a transverse rod of wood or iron,

F F, at either end of the slats E E, Src., conlined to the same by a rubber band, ff, or

similar device, which passes round each end of a rod, F, and bar D. The spring C is shownl curved because drawn down by the levers or springs B-B.

The operation ot' this improvement is as follows: The weight being applied upon the slats E E, &c., the pressure is divided by the blocks c c between the bars D D and the supporting-levers or springs B B B B and the steel springs C (5.

That I claim as my invention is- The slats E provided with the elongated slots z and holes s, in combination with the rod F, rubber band j', and bars D provided with pins u, substantially as and for the purpose set forth.

In testimony that I claim the foregoing improvement in spring bed-bottoms I have hereunto set my hand this 21st day of July A. D. 1873.

BENJAMIN H. OTIS.
